Douglas, A.W. & Hyland, B.P.M. (1995) Flora of Australia 16: 473. Type: Timber Reserve 1230, Boonjee Logging Area, Mt Bartle Frere, QLD, 9 Jan, 1980; B.Gray 1611; holo: QRS; iso: BRI, CANB, DNA, HO, K, L, LSU, MEL, MO.
Oak grain in the wood and a corresponding pattern in the inner blaze.
Oak grain in the twigs. Up to eight leaves in each whorl. Leaf blades about 6-10 x 2-5 cm. Midrib raised on the upper surface.
The centre flower in each head or cluster usually hermaphrodite, the surrounding flowers usually male. Tepals glabrous outside, villous near the base on the inner surface, about 8-9 mm long. Staminal filaments about 4 mm long, attached to the base of the tepals. Hypogynous glands absent. Ovary sessile, villous, about 2 mm long, ovule one. Style glabrous, about 6 mm long. Stigma terminal, +/- 2-lipped.
Fruits globular or depressed globular about 2.1-5 x 1.8-5 cm. Endocarp pitted, very hard, up to about 5-10 mm thick, with large longitudinal ribs intruding into the seed. Seeds about 1.4 x 1.2 cm, one per fruit. The rat-eaten remains of the seed coats normally persist under large trees.
Cataphylls narrow lanceolate, about 0.7-1 cm long, numerous (about 20-40) produced before the first true leaves. First true leaves about 8 x 2.5 cm, produced in a whorl of about 4-6. Margins smooth or toothed. At the tenth leaf stage: leaves usually in whorls of three (sometimes five). Cataphylls about 3-5 mm long, spirally arranged on the internodes between the whorls of leaves. Internodes about 7-9 cm long but probably dependent on the growth conditions experienced. Leaf blade elliptic to slightly obovate, about 85-95 x 24-29 mm, apex apiculate to mucronate, base cuneate, petiole about 6-8 mm long.
Distribution and Ecology
Endemic to NEQ, known only from the Thornton Peak area, Pieter Botte Logging Area and the western slopes of Mt Bartle Frere. Altitudinal range from 450-1450 m. Grows in well developed upland and mountain rain forest.
